A couple of students over at MIT apparently took this picture with a rig that cost them less than $150 total:

The two students (from MIT, of course) put together a low-budget rig to fly a camera high enough to photograph the curvature of the Earth. Instead of rockets, boosters and expensive control systems, they filled a weather balloon with helium and hung a styrofoam beer cooler underneath to carry a cheap Canon A470 compact camera. Instant hand warmers kept things from freezing up and made sure the batteries stayed warm enough to work.

Of course, all this would be pointless if the guys couldn’t find the rig when it landed, so they dropped a prepaid GPS-equipped cellphone inside the box for tracking. Total cost, including duct tape? $148.

Ridiculous. So that shot above, what’s the deal with that?

The picture you see above was shot from around 93,000 feet, just shy of 18 miles high. To give you an idea of how high that is, when the balloon burst, the beer-cooler took forty minutes to come back to Earth.

And just in case you want to try this at home, they will be posting instructions here.
